This is my go-to energy gel when I need a real caffeine boost. In my experience SIS isotonic gels help with stomach problems on longer rides. I really like the taste toi!

FORMULATED BY SCIENCE
Cognitive function declines as exercise duration increases and fatigue begins to set in. Caffeine boosts mental performance by improving focus and alertness as well as improving various aspects of physical performance such as explosive power and repeated sprint performance, making it vital for final pushes in training and competition.
IMPROVED COGNITIVE FUNCTION
Caffeine improves focus, alertness and decision making
IMPROVED COGNITIVE FUNCTION
Caffeine is shown to improve focus and alertness during exercise and periods of fatigue. Fatigue impacts decision making which is detrimental to performance in the later stages of competition, regardless of the sport. Ingesting caffeine during the final stages of exercise ensures mental clarity and reduces perceived exertion when either training or competing .
GO Isotonic + Caffeine provides a mental boost when you need it.
PHYSICAL BOOST
Caffeine improves power output and increases time to exhaustion
PHYSICAL BOOST
Caffeine has been shown to enhance various aspects of physical performance, including time to exhaustion, explosive power and repeated sprint performance. These elements of exercise are vital in the final stages of an endurance event where it can all come down to the wire.

A great taste and a brilliant item to have for long race events. I found these gels very good when I ran at the Southampton Marathon in September 2021. It was a very hot day and a course which had quite a bit of elevation. The gels came as a valuable boost when I was flagging during the second half of the race.

Effective. Caffeine is gentle (as opposed to coffee per se or caffeine tablets). Taste and texture are OK but in some ways irrelevant.

Ottimo spunto, aiuto, quando serve quel pò di energia rapida in più: prima di una salita, di uno scatto o di tratto impegantivo per intensità o pendenza. Non particolarmente dolci, a me piacciono molto. Bere sempre due o tre sorsi di idrosalina o di acqua dopo l'assunzione.

Il prodotto è buono. Occorre ricordarsi che non essendo isotonico come gli altri gel della linea Go Energy occorre prendere dell'acqua dopo l'assunzione
